The Riser Tensioner Problem — and Why NL1 Solves It

Degradation of hydraulic fluid in direct acting tensioner systems has been a documented issue in the offshore industry. Conventional water-glycol fluids can form sticky, high-viscosity black residues containing metal fines under certain operating conditions — residues that can deposit around sealing elements and accumulate in anti-recoil valve internals, creating a critical system failure risk. HOUGHTO-SAFE® NL1 has been specifically formulated to minimise such residue formation and maintain stable pH over a 5-year service period — validated in long-term OEM cylinder tests.

Features & Benefits

Feature Advantage & Operational Benefit
Passes Def Stan 91-110 Annex D — 40:1 compression ignition ratio Certified fire resistant performance — complies with defence and offshore fire resistance specifications for safety-critical hydraulic systems
Very high lubricity — validated in long-term OEM cylinder tests Protects riser tensioner cylinder bore surfaces and sealing elements from accelerated wear — extending cylinder service life and reducing overhaul frequency
Excellent pH stability for 5 years or more Prevents the pH-driven degradation and black residue formation that causes anti-recoil valve failure in conventional water-glycol tensioner fluids
Can be used as a preservation fluid for up to 5 years Dual-purpose — active tensioner fluid and long-term preservation fluid — reducing the number of products required for riser tensioner system management
Cefas D OCNS Rating Environmentally acceptable for maximum discharge — compliant with UK CEFAS and global offshore environmental discharge requirements
Compatible with most commonly used elastomers Avoids seal compatibility issues in standard riser tensioner seal materials — note: avoid PU and FKM/FPM seal materials
Corrosion resistant in liquid and vapour phase Protects cylinder bore surfaces — including uncoated, untreated low-alloy carbon steel — from corrosive wear under lower pH operating conditions
Compliant with global environmental regulations Suitable for offshore operations in all major drilling jurisdictions worldwide

Super cute landing space for keys
Color: White 1 Pack, Size: 8" x 8" x 1.8", Color: White 1 Pack, Size: 8" x 8" x 1.8"
I always have trouble finding my keys and so it’s been very helpful to have a dedicated spot to easily throw them in when I get home. At first I thought it would be too big but it’s the perfect size for two wallets and keys, and it’s good quality albeit a bit expensive. The gold isn’t too shiny either, it’s a nice touch and it really reduces the look of clutter on your surfaces and helps it look more organized. It also doesn’t slip around.
