The Normand Installer (built in 2006) is a multipurpose deep-water construction vessel (SBM Offshore design). Efficiency, redundancy, safety and versatility are the prominent qualities, enabling her to outpace all other vessels in her category and allowing in most cases for the mobilization of only one vessel rather than several to execute the same scope of work. In addition, these characteristics make the Normand Installer suitable to compete with larger, more expensive vessels for a number of applications.
The AHV capabilities of the Normand Installer (300 t bollard pull) allow her to install mooring systems and hook-up floating units efficiently. The additional upper deck doubles the storage capacity and working area and allows simultaneous operations to take place. This relatively compact and powerful (23 MW) vessel remains a light solution considering the variety of heavy construction works she can handle and the range of water depths in which she can operate (up to 3,000 m).
Redundancy is compulsory to limit stand-by time and is implemented for the Normand Installer with the DP3 feature, the two Work Class ROVs, the two independent Heave Compensation systems (250 t offshore crane and 175 t under deck AHC system), two over boarding means for heavy loads (250 t crane and 350 t stern A-frame), and five deep water lowering means (four winches 200 t / 2 x 400 t / 500 t and the main offshore crane).
The additional upper deck allows personnel to work clear from the wires or chains running under tension on the lower / working deck. The DP3 standard for dynamic positioning offers maximum safeguards in marine operations. Safety in design is also enhanced by compliance with latest DNV rules, US Coastguard for foreign flag ships, Norwegian Maritime Directorate and international rules.
Safety in operations is the main focus of the marine crew provided by Solstad (in which key functions are held by Norwegian nationals) and of the experienced offshore work staff provided by SBM Offshore.
The Normand Installer combines the advantages of an AHV, a construction vessel with an offshore crane and additional upper deck not affected by wire and chain operations, and a working barge offering a flat and versatile upper deck to store and easily mobilize / demobilize all kinds of equipment. The reinforced moon pool can accommodate a Vertical Laying System, the upper deck allows for a Horizontal Laying System, and the hull contains a 2,000 t carousel.
The vessel can therefore perform full field development activities such as:
- installation of mooring systems;
- hookup of floating units;
- installation of deepwater subsea structures (manifolds, X-mas trees, CDUs, foundations, etc);
- installation of flexible flowlines;
- installation of risers or umbilicals in vertical or horizontal mode;
- installation of electrical cables in vertical or horizontal mode;
- installation of TLPs using the SBM Offshore tendon installation tower;
- saturation diving with a portable saturation diving system that can be easily mobilized on the upper deck without interfering with wire and chains routings.
The Normand Installer is owned by Normand Installer SA, which is a Joint Venture Company of SBM Offshore and Solstad.
