Safety that keeps production running

HSE consulting for shipyards and industrial plants, led by people who have run safety on site. Based in Altınova, Yalova, and working wherever your project is.

Discuss your project Watch the Tekfen confined-space drill

We put experienced safety leadership where the risk is: on the slipway, inside the tank, under the load. Our team has run HSE on powership construction at three Turkish yards, on the first sixteen YTKB patrol boats, and on refinery and heavy-lift projects at home and abroad.

Our clients are shipyards, plant owners and the contractors who work for them, often with multinational crews that need one safety standard. We advise, engineer, audit, investigate and train, and we bring digital tools that keep it running.

Nexus HSE is based in Altınova, Yalova, in one of Türkiye's shipbuilding regions. Sancak OSGB, now part of Nexus HSE, has served more than 400 companies since 2013.

What we do

Every engagement is led by a senior consultant who has done the job in the field.

  • HSE consulting and project HSE

    Senior HSE leadership for complex, multinational projects: set up properly, then run on site every day.

    ISO 45001, 14001 and 9001 systems, project HSE organisation, permit-to-work for hot work, confined space, height and excavation, and daily supervision with live reporting to management.

  • Risk engineering and process safety

    Find the failure before it finds you.

    HAZOP, LOPA, FMEA and bow-tie studies, Seveso III and ADR compliance for plants, ports and terminals, gas-free and scaffold safety in yards and ports, and job hazard analysis matched to each project's methods.

  • Audits and insurance surveys

    Pass the underwriter's survey, and hand over a technical file that earns better terms.

    Pre-surveys against international insurers' risk-engineering criteria, findings closed before the surveyor arrives, HSE maturity assessments, ISO audits and compliance checks of lifting and pressure equipment.

  • Incident investigation and crisis management

    When something goes wrong: contain it, find the root cause and stand behind the findings.

    Root-cause analysis of accidents and near-misses, court-appointed expert reports, crisis-desk leadership for fire, explosion, storm and tanker emergencies, crisis communications and psychological support for affected workers.

  • Training and drills

    Courses, full-scale drills and leadership programmes built from real field records.

    Nexus Academy

  • Software, AI, animation and games

    Field knowledge turned into tools crews use: document compliance, site control, visitor briefings and training built from your own site.

Nexus Academy

Training that changes what happens on site. It is taught by people who ran these operations, using recordings from our own drills and investigations, and we judge it by what crews do afterwards.

Field courses. Basic OHS, work at height, confined space and safe lifting, in theory and in practice.

Drills and crisis simulations. Fire, earthquake, storm, industrial accident and search and rescue, staged on your site.

Leadership and safety climate. Workshops for managers and supervisors, with measurable HSE targets.

We also train and supply competent personnel: HSE specialists, scaffold inspectors and erectors, forklift operators, welders, fire teams and search and rescue teams.

Software, AI, animation and games for safety-critical work, grounded in what actually happens on site.

PEK Compliance

An HSE document engine. Upload a workplace's paperwork and PEK works out which documents each job requires, generates the internal forms and checks everything against current regulation. It catches an under-18 worker on a restricted job, a job that needs a vocational (MYK) certificate the worker lacks, missing documents and training certificates that don't add up.

  1. Documents uploadedStaff list, certificates, medical reports
  2. Rules matchedJob code, MYK, age, hazard class
  3. Gaps flaggedUnder-18 workers, missing or doubtful papers
  4. Forms generatedAn inspection-ready file

DÖF Panel

Non-conformity and corrective-action tracking from finding to close-out, with owners, deadlines, photo evidence and a full audit trail. In live use on multi-company HSE operations.

Safe Yard

Digital control for shipyards and plants. Every work permit is checked against its work order, active personnel on site are tracked live, and supervisors upload photo evidence from the field.

Visitor registration

A one-to-one video of your site becomes the visitor briefing. Guests receive a QR code or link by email and watch it before they arrive, and the registration program records each visit.

  3. Site videoWatched before arrival
  4. Logged entryEvery visit on record

Findings into games

The non-conformity an HSE specialist records becomes a short simulation or game level, and work instructions become playable. Crews learn from the last finding on screen, not on site.

  1. Finding recordedBy the HSE specialist
  2. Scenario builtThe real mistake on site
  3. Game levelSimulation and instruction
  4. Crew practisesThe mistake stays on screen

Training on your own site

Your actual workplace, rebuilt digitally, becomes the setting for training. Crews learn the routes, hazards and procedures of the site they will work on, not a generic one.

  1. Site dataPlans, photos, video
  2. Digital modelA one-to-one copy
  3. Routes and hazardsRisks marked up
  4. Site-specific trainingWhere they will work

The AI reads and suggests. Rules and qualified people decide.

That principle runs through everything we build for safety-critical work. The same software, AI, animation and game skills are available for projects outside HSE.

OSGB services in Türkiye

For smaller workplaces, our ministry-authorised occupational health and safety unit provides what Law No. 6331 requires: safety specialists, workplace physicians, health personnel, medical examinations and mobile health screening on site.

Authorised since 2013, formerly operating as Sancak OSGB.

How we work

  • People before scheduleAccidents and occupational disease are preventable. No deadline is worth a life.

  • ReliabilityWe deliver what we promise, to standard and on time. If something is going to slip, you hear it from us first.
