Shipyards benefit from using Roxtec seals for external deck penetrations

Mechanical cable and pipe seals are quick to install and do not need curing time.

There are many good reasons for choosing Roxtec sealing solutions for external deck penetrations. The seals are watertight and corrosion-resistant. They are also easy to install from only one side of the deck. And they are extremely durable.

Shipbuilders know the importance of sealing every little deck penetration onboard, including cable penetrations for the lighting and speaker systems. External deck areas, which accommodate tanks and cargo, must be watertight and gas-tight, and other external decks, like accommodation bulkheads, trunk decks, and passageways, must be A0 fire rated or at least weathertight. The new vessels, LNGs, LPGs, carriers, tankers and container ships, will sail for years through varying temperatures, heavy rains and storms with huge salty waves.

Some shipyards use compounds to seal while others create their own versions of raised deck penetrations. Compounds often need curing time and raised penetration decks may require  welding of a complicated blend of steel materials or need time-consuming installation work. There are, however, alternatives that challenge traditional methods for sealing penetrations.  

Innovative and reliable seals 

With mechanical cable and pipe seals from Roxtec, a single worker can perform quick single-side installations and easily verify quality for long-term safety and operational reliability. The seals are ready for use directly after installation. Furthermore, Roxtec seals are openable, which makes it easy to handle equipment changes and cable and pipe replacements. Given the increasing safety demands from the development of modern vessels and alternative fuels, the need for reducing insurance cost, and the rising labor costs, it is time for ambitious shipyards to try to find safe and efficient solutions.

Tested and certified solutions

Roxtec seals are tested to all relevant marine standards and certified by all major classification societies, including DNV, ABS, LR, CCS, RINA, and KRS. According to several test reports, the seals withstand gas pressure, temperature cycling, shockwaves, and vibrations. They are developed to support sustainability efforts and simplify maintenance, and they have all required material classifications for use in harsh marine environments.

Roxtec H2 seal – for easy installation of lighting cables

Roxtec offers several round seals, such as Roxtec R transits for multiple cables and pipes, the Roxtec RS seal for single cables or pipes, and the versatile Roxtec H series which is available in different sizes and for up to eight cables or pipes. The Roxtec H2 seal, for example, is perfect for external deck lighting cables. It allows for passing two cables, for example the cable that comes out to connect to the lighting fixture and the cable that returns back inside again. The Roxtec H2 seal with SLA sleeve has a Class A fire rating in accordance with the IMO 2010 FTP Code. It is proven gastight to 1.5 bar (catastrophic) and watertight to 2.5 bar (catastrophic).

Roxtec H seals are easy to install in a wide range of sleeves and structures. They provide user-friendly flexibility and certified protection against fire, gas and water. You can even have them tailor-made for specific requirements. The Roxtec H seals have fittings and fasteners in acid-proof stainless steel and are equipped with Multidiameter™, the Roxtec invention for adaptability to cables and pipes of different sizes based on removable rubber layers.

So, why not include Roxtec seals in your shipyard standard to increase safety, capacity, and speed of installation all while acting in a cost-efficient manner?
