Products and services

• OPTIMOOR Mooring Analysis Software World-leading ship mooring analysis software licensed globally, offering 2D/3D modelling capabilities for static and dynamic analysis, wave response, ship-to-ship operations, tsunami effects, and passing ship interactions. Based on OCIMF recommendations and procedures, designed for vessel and terminal personnel, port designers, and naval architects.
• OPTI-LIFE Rope Life Prediction Software Rope life prediction software that predicts residual rope life in mooring applications using loading history and rope type as inputs. Forms the basis of an automated rope monitoring system with load cells, providing used and remaining rope life information and warnings for timely replacement.
• Fibre Rope Modeller (FRM) Comprehensive rope modelling program that derives rope properties from rope construction, basic yarn data, and secondary yarn properties. Determines rope strength, predicts tension-tension fatigue life and stress rupture, determines elongation and creep elongation, establishes static and dynamic modulus, and provides rope diameters and unit weights.
• Engineering Consultancy Services for Rope, Textiles and Marine Systems Engineering consultancy for ropes, textiles, and marine systems including mooring system global time-domain analysis, concept development, design optimisation, detail design, independent testing, failure analysis, expert witness, and global structural analyses. Sold to enterprise clients in offshore oil and gas, LNG, marine renewables, and ports/terminals.
• TTI Testing Independent Mechanical Laboratory Services World-renowned independent mechanical laboratory specialising in custom testing of materials and assemblies for wire ropes, fibre ropes, chains, electromechanical cables, hoses, and related interface components. Offers tensile testing up to 2,000kN, bend fatigue, cyclic bend testing, abrasion testing, forensic analysis, and qualification testing of new products to industry standards or customised to specific service applications.
• Approved Optimoor Face-to-Face Training Courses TTI-delivered approved Optimoor training courses delivered face-to-face for 1 or 2 days, covering static, dynamic, wave response, and ship-to-ship topics with hands-on exercises and certificates upon completion.
• TTI Marine Renewables Consultancy Subsidiary consultancy providing advanced technical solutions and consultancy for the offshore renewables market, including station-keeping solutions design, development, testing, and qualification for floating offshore wind, wave, tidal, and hydrokinetic technologies.

Scale indicators7 records

Recent moves9 records

Expansion highlights6 records

Broad incumbents

• COWI: COWI is a large engineering consultancy with offshore wind and marine infrastructure practices. Comparable to TTI on offshore wind mooring design and port/terminal engineering, but at much broader portfolio scale and with global resources.
• DNV: DNV is a classification society and maritime advisory that TTI actively partners with on industry standards. DNV's offshore engineering and advisory services overlap with TTI's mooring, terminal design, and floating offshore wind advisory work at a much broader portfolio scale.
• Element Materials Technology: Element is a large independent materials testing and product qualification services provider. Comparable to TTI Testing Ltd on tensile, fatigue, and materials testing services but operating a global laboratory network versus TTI's single Wallingford facility.
• Royal HaskoningDHV: Royal HaskoningDHV is a global engineering consultancy with significant marine, port, and offshore wind practices including terminal and mooring design. It overlaps with TTI on port and terminal mooring analyses but operates at significantly larger scale.
• Wood Group: Wood Group is a large offshore engineering and consultancy firm serving oil and gas, marine, and renewables clients. It overlaps with TTI on offshore engineering services and floating offshore wind advisory but at much larger scale and scope.
• Bureau Veritas: Bureau Veritas is a global testing, inspection, and certification (TIC) company that overlaps with TTI Testing on independent mechanical laboratory services and with TTI on marine advisory and certification work. A potential strategic acquirer or broad incumbent peer in testing.
• BMT Group: BMT is a large maritime engineering consultancy covering ship design, offshore engineering, and marine environmental services. It is comparable to TTI as a broad marine engineering incumbent offering mooring and terminal design services at greater scale and breadth.

Direct peers

• Vryhof: Vryhof specialises in mooring and anchoring solutions for offshore vessels, including deepwater and floating wind. It is directly comparable to TTI on mooring system design, qualification, and engineering services for offshore operators.
• Orcina: Orcina develops Orcaflex, the leading time-domain mooring analysis software used globally by naval architects and offshore operators. It is the closest direct competitor to TTI's OPTIMOOR in mooring analysis, competing on dynamic analysis, ship-to-ship, and floating offshore wind modelling.

Others

• Bridon-Bekaert Ropes Group: Bridon-Bekaert is one of the world's largest rope manufacturers (wire and synthetic) and a member of TTI's MESAT project consortium. Adjacent rather than directly competing, Bridon-Bekaert supplies the mooring ropes that TTI qualifies and analyses.
