Objetivo The oil industry presently bases their intervention scenarios on modified and adapted maintenance methods developed for onshore or shallow water intervention which seldom show optimum and economic solutions.To increase efficiency and economy for deepwater intervention new methods have to be developed.By evaluation the possible market potential and the technical features of the SOLS, the following groups of systems - MTS component families - have been selected which seem relatively logical to be performed by a system based on the SOLS concept.- Workover/Production/Transportation- Downhole operations/Maintenance- Subsea intervention on tree and template- Pipeline related tasks.The valuation of the features of the SOLS compared with the a. m. groups showed that methods of subsea operation, totally different from the SOLS principle, require so many modifications that a totally new development would be necessary. This was not the intention of this study.The conclusion of the beforesaid is that the MTS consortium concentrated their development work on those MTS concepts justified by criterias as :- SOLS features adaptable to proposed MTS,- multipurpose functional capacity of one system,- market potential and- economic operation of the system.The loading of live crude, theinjection, the pipeline related tasks and an installation and retrieval system have been identified to be of most interest.The following ranking shows the priority given to all before mentioned concepts during the following examination :1. Pipeline Intervention System : PINS2. Module Installation and Retrieval System : MIRS3. Live Crude Loading System : LCLS(subsea storage concept)4. Injection System : INS(combined live crude loading).In order to concentrate on the most promising concepts in the future subsea market, the MTS consortium decided to focus their ongoing development works on the concepts 1 to 3.These system including their subsystems were conceptually defined and presented.It is envisaged to focus ongoing development works on these three systems within a second R&D phase (MTS Ph. II) which includes the design and testphase.The project has finally been abandoned because of technical and financial risk.The objective of this project was to develop a Modular Transfer and Service System on the basis of the know-how gained from the SOLS development project (Subsea Oil Loading System).The system to be developed is to serve not only for loading, but also for unloading liquids or similar substances from tankers or other vessels. For unloading applications, the following was considered during the Concept Study/MTS I:- Production auxiliary materials to be pumped into injection wells .- Pressurized water to be provided for cleaning the subsea facilities.- Ballast materials to be transported and pumped into foundations or covering of pipelines or other subsea facilities.In addition, the concept of the SOLS system has been modified and fitted with adapters for further transportation, installation, inspection and maintenance work like through flowline servicing and pig launching.The feasibility of the SOLS principle for the applications suggested here was therefore be examined in the framework of the Concept Study. From this a modular system was developed, which could easily be adapted for the different transfer and service tasks by modification of the individual components.
