On this website you will find a methodology of designing a mooring system for a semi-submersible. Detailed information on mooring systems, mooring designs and mooring materials can be found. This website also displays semi-submersibles, where they are used for and how the semi-sub works.

This website presents a philosophy; our view on how mooring systems for Spar platforms should be designed. Although it is designed to derive a Spar platform anchor system, it can also be applied for other anchored structures. The purpose of this site is to provide a guide-line for designers or design teams. This site does not go in to much detail; it does not give theoretical background on subjects as the determination of the anchor-line thickness or the dimensions of the anchors.

There are several ways to design an offshore mooring for an FPSO. On this site a mooring is designed for an FPSO. The design steps that are taken in this example are explained on this site step by step.

The SPAR is a deepwater drilling and production platform. Spar technology has been used to support manned and unmanned operations in offshore environments for over thirty years. The SPAR platform uses ‘‘dry-tree’’ technology, where the wellhead equipment is principally located on the platform rather than on the seabed, reducing the cost and time involved in common maintenance work.

The website provides an easy and quick overview of possible mooring systems for your FPSO. There are numerous systems available and a description of most of these can be found on this website. The selection page is a tool which tells you in just a few steps, what is a suitable solution to moor your FPSO. On the forces page you can gain insight into the forces which need to be compensated by the mooring system of a vessel.
