Thruster Solutions

Stop Leakage, Water Ingress & Seal Suppor

Common Thruster Challenges

Thruster systems operate under frequent manoeuvring, load variation, pressure changes, seawater exposure, and demanding seal conditions. Over time, these conditions can affect lubrication performance, increase wear, and lead to oil leakage, water ingress, reduced seal stability, or operational uncertainty.

Oil Leakage

Seal leakage can increase oil consumption, create maintenance pressure, and affect thruster operation.

Water Ingress

Water contamination may reduce lubricant performance and increase wear, corrosion risk, or oil instability.

Seal & Wear Issues

Repeated manoeuvring, vibration, and fluctuating loads can affect seal stability and component life.

Operational Instability

Thruster-related issues can create uncertainty during manoeuvring, station keeping, or planned operations.

Built Around  Thruster Operating Conditions

Thruster systems operate under demanding and variable load conditions that may affect sealing, lubrication, and long-term component performance.

Key operating factors include:

  • Frequent start-stop operation
  • High load variation during manoeuvring
  • Directional changes and vibration
  • Seal exposure under changing pressure conditions
  • Lubricant stress, temperature variation, and contamination risk

Why it matters:
Over time, these conditions may contribute to oil leakage, seal wear, reduced lubrication stability, and increased uncertainty around thruster reliability.

A Progressive Solution Structure

The TH range is structured from preventive protection to stronger sealing support for thruster systems.

The range is built around four application levels:

TH Guard — preventive protection for stable systems
TH Seal Core — standard support for smaller leakage cases
TH Seal Plus — reinforced support for moderate leakage or demanding conditions
TH Seal Max — maximum support for severe leakage cases

Why it matters:
This structure helps operators identify a relevant starting point based on thruster condition, leakage behaviour, and operating demands.

Product Selection Factors

The right product depends on the actual thruster system and operating situation.

Typical selection factors include:

  • Leakage behaviour and development over time
  • Thruster oil volume
  • Lubricant type currently in use
  • Seal condition and wear pattern
  • Operating profile, manoeuvring intensity, and load variation
  • Service objective before next maintenance window or dry dock

Why it matters:
These factors help determine whether the focus should be preventive protection, standard sealing support, or stronger leakage mitigation for demanding thruster conditions.

Technical Review Before Application

Before application, the thruster system should be reviewed to ensure the correct product selection and quantity.

Typical review points include:

  • Thruster oil volume
  • Current leakage level
  • Lubricant type and viscosity
  • Seal condition and service history
  • Operating profile and load variation
  • Filtration setup and system cleanliness

Why it matters:
A technical review helps reduce application risk and ensures the selected TH product is matched to the actual thruster condition and operating environment.
