Balmoral Subsea Insulation

Balmoral Subsea Insulation, a division of Balmoral Comtec Ltd, was launched in 2017 to complement the company’s existing shroud and doghouse insulation product lines. Significant investment was made in new facilities to build on the experience gained through the company’s previous insulation and pipe coating business, Balmoral Webco, which was operational 1990-1997.


Field or factory application

Balmoral designed and created specialised field application units (FAU) that are effectively containerised ‘factory in a box’ solutions designed for global deployment. The FAU’s are fully autonomous with minimal reliance on yard support for onshore, site-based coatings. They are equipped to apply Balmoral Elastotherm systems to meet and exceed client insulation and flow assurance requirements.

Underpinned by the company’s industry-leading reputation for customer focus and project governance, Balmoral’s highly skilled and experienced supervisory and application teams are trained to ensure a consistently high level of customer service is delivered. This ensures professional, controlled and on-time completion of insulation activities at client locations around the world.

Design and testing

Balmoral Subsea Insulation draws on the company’s extensive engineering experience and comprehensive R&D programme to offer FEA or CFD analysis of project design parameters to ultimately provide the most cost effective coating solutions. Early dialogue with clients means that optimum fit for purpose, through life, solutions can be identified and implemented.

New, state of the art, technical and subsea test centre facilities offer extensive laboratory and test capabilities to ensure all materials meet stringent industry requirements, including ISO 12736.

Applications and advantages

Balmoral Elastotherm insulation systems are suitable for use both as cast-in place ‘wet’ insulation on ‘Christmas trees’, manifolds, jumpers and spool pieces, and also in modular systems such as connectors and flange covers. The company offers subsea insulation systems suitable for a wide range of applications, including:

  • Excessive depth/hydrostatic pressure, eg;
    up to 3000 msw for Elastotherm™ S1 & S2
    up to 7000 msw for Elastotherm™ T & HT
  • High hot/dry service temperature, eg;
    up to 150°C for Elastotherm™ S1 & S2
    up to 125°C for Elastotherm™ T
    up to 135°C for Elastotherm™ HT
  • Hot/wet conditions, eg;
    up to 135ºC for Elastotherm™ S1 & S2
    up to 90°C for Elastotherm™ T
    up to 120°C for Elastotherm™ HT
  • Where constant insulation properties are required through service life
  • Where in-service fatigue or high coating strains during installation are anticipated

Specific advantages of Elastotherm solid systems include:

  • Immunity to hydrostatic compression due to the absence of hollow glass or polymer microspheres
  • Combined insulation and anticorrosion performance
  • Outstanding tensile and impact performance
