THE FLEET

DP2 Highland Spirit

Mobilised with an 80 tonne capacity, single tower over mid-ship moon pool.  Key features include; mechanical handling of drill string (to NORSOK standard), 4m heave compensation, wireline CPT, piston, push sampling and rock coring with comprehensive offshore core analysis and photography capabilities.  Her exceptional DP performance can deliver a borehole in 15m of water in a highly dynamic environment.

To complement the spread she is mobilised with a full geophysical site survey package, large A-frame for safe handling of seabed CPT, sampling tools and inspection class ROV making her a truly integrated site investigation vessel, unique in her field.

Kommandor Stuart

A proven ice class multi-role survey vessel mobilised with a high specification geophysical spread capable of acquiring full single pass analogue and digital seismic data to standard Norwegian requirements, seabed CPT, sampling and environmental photography and ROV to 3,000m in support of de-risking semi-submersible and jack-up rig siting and drilling including field development programmes.

Kommandor Calum

A game changing twin engine single screw, site investigation vessel.  At 80m she has been specifically designed to maximise the voluminous nature of the heavily built hull for safe, sustained and comfortable operations. Capabilities include 2D exploration, 2DHR, ship-fit compressors and air storage, SBP arrays, deep water MBES with dedicated mid ship A-frames and crane for handling seabed geotechnics, environmental and ROVs.  There is even a nine seater cinema and a sauna!
