AMEC Marine Construction(AMEC)

AMEC Marine Construction(AMEC) is an international marine construction company with Shipyards around the Globe specialising building specific marine projects for a variety of international clients. It was recently commissioned to construct an install an Offshore Oil and gas production platform for an international consortium.
The Project/program
To construct and installation of an Offshore Oil rig platform to the North Sea.
Two four-leg jackets one for the production platform and one for the Accommodation. One accommodation (Deck) platform for the crew quarters and offices with five levels.
One production (Deck) platform with four decks for the production equipment
Jackets: when both jackets structures have been completed skidded onto two barges and towed to the North Sea oil field location. Platforms: both platforms put onto barges and towed out to the jackets location.
The budget for the Project is US$ 550m, and the platform should be installed before the winter weather closed in on the area, therefore no later than 30th August 2024, and delivered for Operation no later than the end of September. After that day is an operational lost profit penalty of US$ 300,000 per day. Since the location of the oil field (North Sea) and the unique design demands of the Project, the construction should start at AMEC’s two shipyards on Newcastle upon Tyne, the starting day hasn’t been finalised yet but would be the first six months of 2021.The budget of the Project was estimated on the base that work needs to be done with a 24/7 workload framework, and commission both yards at the hole period of the Project. Also, all the main sub-contractors would be from the UK and Europe due to close links and contracts with the consortium.
The Project manager and the team
Melvin Black has been appointed as the Project manager. He is a 50-year-old project manager with 30 years’ experience in Marine engineering project management. Melvin appointed a full-time team of five managers and ten assistant managers (see Diagram below), which all of them had experience working on similar oil rig platform projects and co-ordinating relevant shipyard managers and staff.
Project/program team Structure
The Project/program plan
Due to the complexity of Project’s time and financial sponsorships, Melvin’s first act with his team was to create the millennium stages, detail activities/tasks, budget spreadsheet for every activity with cost in (US$ millions) from the table below of the project/program which the consortium approved. Also, to create a WBS table of the project/program.

Explanation of the main stages of the Program/Project
• Stage 1
 Finalised Design of Oil rig Platform with the naval architects’ design team and provide final blueprints of the Project to the consortium board. 10 days.
 Project management team: Commissioning Project preparation, scope definition method development, Project reports documentations.35 days
 Creation of project teams Project manager with his allocated managers create the relevant teams and finalised project plan. 20 days.
 Documentation, manual operations documents for Inspections and maintenance, shipyard base load platform utility (including power, water, and air) allocation, Quality inspection management, Sub-contractors operation documents and plan. 10 days.
• Stage 2
 Operation platform (deck) construction with four deck levels or topsides welded together and plated over to contain all the equipment required to run the various production process. Coordinate sub-contractors, yard management, Quality inspection management, Logistics, and weight management. Estimation construction time 1003 days.
 Accommodation platform (deck) construction for the crew quarters and offices with five levels. Estimation construction time 730 days.
 Two four-leg jackets construction one for the Production Platform and one for the Accommodation. Each four-leg Jacket should be fabricated from large rolled steel circular steel sections, welded together and interspersed with smaller tubular members welded to the main legs using prefabricated nodes. Which gives the structure its strength as it tapers from the wide bottom sections to the top smaller section. Construction time for Operation jacket 304 days and the accommodation jacket 215 days
• Stage 3
 Preparation and transportation of Operation &Accommodation platforms when both structures have been completed final weight and balance them onto crane/barges and towed out to the jackets location. Estimation time for preparation 5days, and transportation time 10 days for each of them.
 Preparation & transportation of Jackets when both jackets structures have been completed balance them and skidded individually to their crane/barge and towed to the North Sea oil field allocation. Estimation time for preparation 3 days, and transportation time 5 days for each of them.
• Stage 4
 Installation of both jackets, when arrived at the allocation, slid off the crane/barge and settled in the water coming gradually to the vertical position over the capped reservoir well, sinking as it is slowly de-ballasted. Estimated time 5 days for each Jacket.
 Anchoring jackets Once in the right position the piles are driven through the pile sleeves and mud flaps by a pile driver on a barge. Then cement is poured into the gap between the piles and the pile sleeves acting as an efficient grout and effectively securing the whole structure to the seabed at a depth of 480m.Installationtime 5 days for each Jacket.
 Installation of Operation & Accommodation platform A heavy lift barge crane swings them over the matching jacket, and both are welded together with great accuracy, a couple of mm between the mating faces being the norm. The offshore commissioning activities are carried out to prepare the platform for the testing of the processing systems. When that stage is finished, then the accommodation deck installation starts with the crane repeating the process and the offshore commissioning activities are carried out for the crew and office quarters. Installation time 5 days for each platform.
• Stage 5
 Installation connection and preparation of Subsea pipes to subbed and connecting station pipes to weld to the Operation platform. Duration 15 days.
• Stage 6
 Testing platform’s processing systems as the production platform is installed over the wellhead and the risers connected to the production manifolds the final pipe in the reservoir perforated by small explosive charges. This allows the orderly high pressure flow of gas and fluids to come up the riser to the production manifolds and oil, gas and water systems going through rigorous testing before the platform commissioned and at the same time testing all the departments of the accommodation platform are operational. Duration 30 days for the Operation Platform and 10 days for the Accommodation platform days.
• Stage 7
Transferring Ownership of the platform to the client and the Oilrig crew.
Duration 4 days.
Main consideration points for the Project/program.
• The project manager and the management team must collect the finalised design documents before starting the project scope and objectives and creating the relevant project teams
• Project teams must create the project reports development of project delivery, detail budget plan, and the documentation manuals.
• Construction can’t be started until all the documentation manuals are developed.
• Finalised Design of Oil rig Platform, must be finished before the creation of project teams.
• Crane/Barge, tow boats US$300,000 per day
• Crane/barge, towboats and barges must be booked two years in advance with details of the rent period, since penalty tariffs.
• Transportation, all transportation for both platforms and Jackets, should be done between May and August due to weather restrictions.
• Installation of Platforms for both Jackets and platforms should be Operation first and then Accommodation.
• Anchoring the jackets must take place before platforms installation
• Installation connection and preparation of Subsea can be done when the Operation Platform has been installed of Jacket.
