Subsea Installation, Heavy Lift And Transport Vessels Show Muscle In FPSO Market

Having added a unique multi-purpose offshore installations vessel and a pow- erful floating crane to its fleet, the Smit

International Group is increasingly busy on installation heavy lift and heavy transport projects associated with


Smit Pioneer, formerly a LASH carri- er, was acquired and converted by Smit in 1999. The vessel represents a new concept for multi-purpose offshore installation tasks. This large, dock-type vessel is designed and equipped to remain on station for extended periods, having an unusually high degree of self- sufficiency.

The multi-purpose vessel's primary roles include: installation of moorings, diverless tie-ins, well servicing, flexlay, manifold and riser installation, ROV support and long haul cablelay.

The vessel's equipment outfit includes an advanced DP system, two moon- pools, a fully heave-compensated revolving crane (rated at 150/250 tons) and a Super Puma-capable helideck.

Following its extensive conversion program and successful sea trials, the vessel has gained instant acceptance in the global offshore installations market in its new multi-purpose role. The newly commissioned vessel — the first of a new class — started immediately on a contract connected with development of a new field in Angolan waters, and then secured another contract, for work relat- ed to Canada's first FPSO, offshore


Engaged by Coflexip Stena Offshore,

Smit Pioneer undertook a series of

Circle 268 on Reader Service Card installation tasks required within the first phase of the fast-track Kuito devel- opment, in 400 m water depth offshore

Angola. Coflexip Stena Offshore, SBM and ABB are members of the consor- tium responsible for the subsea installa- tions program. Chevron is the field oper- ator.

Smit Pioneer's role, performed during autumn 1999, involved the installation of flexible risers and mid-water arches consisting of buoyancy tanks and coun- terweights. In addition, an 80-ton subsea manifold 20 x 10 x 10 ft. (6 m x 3 m x 3 m) was installed.

Equipment for this project — loaded onto Smit Pioneer at Le Trait, on the

Seine — included a 65 ft. (20 m) diam- eter carousel and Coflexip's VLS (Verti- cal Lay System) reel — located at the aft moonpool. Smit's project team engi- neered a 20 x 20 ft. (6 x 6 m) moonpool plug, required to ensure that the radius of flexible lines remained within the specified parameters.

Smit immediately secured another contract from Coflexip requiring Smit

Pioneer to undertake trenching and lay- ing of flexibles at 312 ft. (95 m) depth in the Terra Nova Field, located in the grand Banks Area, 350 km off St John's,


During April, Smit Pioneer loaded equipment and departed for Canadian waters. The equipment included 12 reels, the Coflexip VLS (mounted at the forward moonpool), a trencher and an


The vessel's operational advantages include: a single platform for all off- shore installation tasks: mooring lines and anchors (plus pre-tensioning); flow- lines, umbilicals and tie-ins; risers, riser bases and manifolds; ROV support; well servicing; and drill support; single mobilization for most mooring systems; min- imum time required for mobilization/demobi- lization/transit; a large deck area and loading capacity ideal for long haul fiber optic cable- lay. In this role, Smit

Pioneer can load and lay 10,000 km of trans- «

Atlantic cable in a sin- f , gle voyage.

Acquired in early 2000, the big sea- going sheerlegs is now the flagship of

Smit's seven-strong fleet of floating cranes.

The capacity and flexibility of this sheerlegs — one of the most powerful in the world — make it ideal for fast-track

FPSO projects. It is able to lift and trans- port integrated units weighing well in excess of 2,000 tons. With this capacity available, those responsible for fitting (Continued on page 73)

Lo-Rez system and the Hatfield-designed acoustic treatment.

The end result of installing Lo-Rez engine mounts and flexible couplings, is phenomenal.

There are now approximately 12000 operational hours on the main engines with no problems to date".
