Location: La Libertad, Ecuador
Client: Oxxo Brenes & Servicios de Ingerniera (for Petroindustrial) Engineering, Tanker Terminal, Sealine and SPM Replacement Sealine and SPM. Project Management, engineering and supply of equipment for installation of a 5.5km long 20” concrete coated pipeline from the site of a new off loading buoy (SPM) to the beach at the refinery at La Libertad. The pipeline was built several km away and launched directly into the sea. Using L&M’s Flowlay® surface towing and installation technique, a 12 hour tow to the field was undertaken and the pipeline then flooded down along the required route corridor, which included curved sectionsThe launch, tow and installation was completed in just 3 days. After installation of a PLEM, a new single point mooring CALM buoy was installed, including the laying and tensioning up of anchors and chains. Location: Camisea Project, Pisco, Peru Client: Pluspetrol Exploracion y Produccion SA Engineering, Bundle Sealines to a Tanker Terminal Camisea Subsea Pipeline Loading System.
Phase 1 - Engineering feasibility study to determine methodologies for installation of 3km flat-pack bundle. The 5000 tonne bundle for LPG products comprised two 24-inch pipe-in-pipe insulated pipelines, one 24-inch pipeline, a 12-inch diesel pipeline and an umbilical cable.
Phase 2 - Project management, engineering and supply of equipment for installation of a 3.2km flat-pack bundle. The bundle was assembled in a continuous length using railtrack and bogies, the track being laid with vertical and horizontal curves through the site of a new processing plant. The buoyancy pipes were configured using the Land & Marine Flow-Lay® method adapted for off-bottom towing. The bundle was pulled down to the shore using land-based plant. A 300 Tonne linear winch was set up on a specially built barge and the bundle pulled offshore into the prepared trench and flooded down into location Location: San Sebastian Bay, Tierra del Fuego, Argentina Client: Pan American Energy SRL and Petrol Servicio Corp SA/ENAP Engineering, Landfall Sealine to an SPM Tanker Terminal Phase 1 - Engineering feasibility study to determine methodologies for a pull ashore from lay-barge of a 2.6km x 18” diameter crude oil export line to replace existing line leading to a Single Point Mooring.
Phase 2 - Project management, engineering and supply of equipment for installation of the 2.6 km pull-ashore of an 18” diameter concrete coated pipe using 300 Tonne linear winch with double purchase capability. Tensioning of mooring system for a CALM Buoy completed using linear winch. Contract included installation engineering. Location: Cantarell Field, Gulf of Mexico, Mexico Client: Pemex (s/c to Stena Coflexip) FSP Mooring System The mooring system and installation of a FSO tanker at the Cantarell Field. The mooring system comprised of 10 No. piled anchors driven into the seabed in 80m of water depth, was linked to the FSO turret by cable and chains. The FSO Ta'Kuntah, a former 366,000 DWT tanker was the first FSO in the Gulf of Mexico.

Location: Cusiana – Cupiago, Colombia Client: BP Colombia Directionally Drilled River Crossings Installation of 5 No. river crossings forming part of the Cusiana to Cupiago 508mm dia trunkline project for oil transportation. Location: Puerto Ordaz, Venezuela Client: Corpoven Directionally Drilled River Crossing Installation of a 1360m x 914mm dia steel gas pipeline crossing of the river Orinoco at Puerto Ordaz. Part of a gas supply line to an industrial complex. Location: EI Tigre, Venezuela Client: Lagoven Directionally Drilled River Crossings Installation of two river crossings forming part of the 914mm dia "orimulsion" trunkline project. Rio Morichal Largo 1000m Rio Tigre 518m Location: River Orinoco, Venezuela Client: Lagoven SA Inter Island, River and Estuary Crossing The fabrication and installation of a 250mm dia x 1.5km steel gas pipelines and positioning in separate trenches. The pipe trenches were formed by dredging prior to pulling pipe into position. Location: Salina Cruz, Mexico Client: Pemex (s/c to Condux) Tanker, Terminals, Sealines and Flowlines Positioning of 1220mm and a 762mm dia. oil lines each 5km long by pulling the pipeline offshore using barge-mounted winches and installation of a Single Point Mooring for 250,000 dwt tankers. Location: Dos Bocas, Mexico Client: Pemex (s/c to ICA) Landfalls Pull ashore of three pipelines, two x 1220mm, one x 914mm from laybarge anchored 1.2km offshore. Pipes pulled by 1200 tonne land based winch set up Location: Straits of Magellan, Argentina Client: Gas del Estado (s/c to ETPM) Landfalls Pre-dredging of a 7km pipe trench at the Southern shore approach on the island of Tierra del Fuego and the pull ashore from laybarge of a 2.5km x 610mm dia steel pipeline. The Northern approach on the Argentinian mainland involved the pre-dredging of an 800m trench and the pull ashore from laybarge of a 500m length of pipe. A 500m length of pipe trench on the South approach was drilled and blasted to remove rock outcrops. Location: Punta del Este, Uruguary Client: ANCAP Tanker Terminals, SPM and Sealine Installation of Single Point Mooring for 150,000 dwt tankers, and construction of associated steel submarine pipeline 914mm dia and 2.6km length. The concrete encased pipeline was constructed onshore, pulled into position by barge-mounted winches and trenched into seabed after pulling. L&M acted as Consulting Engineers.
