The UT 742 is designed and arranged for a wide spectre of sub sea installation works and services; and can also be arranged for light drilling and similar services. We mention:
- Sub sea work and installation at sea bed
- ROV and ROT services
- Laying and handling of anchors and mooring lines for offshore floating production platforms.
- Laying of flexible pipilines on sea bed between oil and gas installations.
- Plowing for pipelines in sea bed, with a pull load of approx. 270 tonnes.
- Towing of production platforms and drilling platforms.
- Handling and installation of construction blocks and equipment.
The work deck is designed and prepared for installation of topside modules with weights up to approx. 25000 tonnes.

M/S "Normand Pioner" is built with two moon pools in ship centre line. The work moon pool has dimensions approx. 7m x 7m, and the ROV moon pool approx 4,5m x 4,5m. The moon pools are located close to the vessel's flotation centre, and are arranged with sea flow dampening compartments. The UT-742 is generally designed and arranged according to "Class III" vessel with two main propulsion machinery plants in separate machinery compartmenst. M/S "Normand Pioner" i equipped and certified as a "Class II" vessel, and is prepared for later conversion to "Class III".
